+We have so far failed to find a good way to determine the stack base.
+It is highly recommended that GC_stackbottom be set explicitly on program
+startup.  The supplied value sometimes causes failure under AIX 4.1, though
+it appears to work under 3.X.  HEURISTIC2 seems to work under 4.1, but
+involves a substantial performance penalty, and will fail if there is
+no limit on stack size.
+
+There is no thread support.  (I assume recent versions of AIX provide
+pthreads?  I no longer have access to a machine ...)
